Answer:

A.) 64

Step-by-step explanation:

The first step is identifiying the original price of the shoes and the discount

Next you will decide what type of equation you will need. For this situation, you would need a subraction equation.

80 - 20% = ?

If you choose to slove with a calculator, don't put 0.2 in the place of 20%. We dont do this because it will result in a different answer. 80 - 0.2 = 79.8.

Now we solve the problem

80 - 20% = 64

The perimeter of a rectangular painting is 364cm . If the length of the painting is 96cm, what is its width?
hram777 [196]

Answer:

The width would be 86cm

Step-by-step explanation:

Perimeter is (Width*2) +(Length*2)

Length is 96, multiply by 2 : 96*2 = 192

Subtract this from the total perimeter (364-192 = 172)

Divide this by 2 to get 1 width value (172/2 = 86)

86 cm

Can someone please help me Factor 4x^2 - 81
Vsevolod [243]

Answer:

(2x-9)(2x+9)

Step-by-step explanation:

This is a difference of squares because it can be written as (2x)^2-9^2

The formula for factoring a difference of squares is a^2-b^2=(a-b)(a+b)

So replace a with 2x and b with 9 giving us

4x^2-81=(2x-9)(2x+9)

How much would $200 invested at 7% interest compounded annually be worth after 5 years? Round your answer to the nearest cent. D
viktelen [127]
The future worth (F) of the investment at present (P) with a compound interest i after n years is calculated through the equation,
                                      F = P x (1 + i)^n
Substituting the known values,
                                      F = ($200) x (1 + 0.07)^5 = $280.51
Thus, the future worth of the investment is approximately $280.51.
